Dr. Forrestal, a senior research officer at Teagasc, heads a lab of nine integrating soil and plant nutrition with environmental loss mitigation. This team provides impactful solutions to the agri-food industry and policymakers, particularly in the synthetic, organic, and bio-based recycled-fertilizer space. His research on urease and nitrification inhibitors for mineral fertilizer is the largest single measure available for agriculture to meet its greenhouse gas and ammonia commitments. He ensures knowledge transfer to stakeholders by publishing research, setting up collaborative field trials and demos with advisory staff, writing articles for the popular press, and using social media.
